Abstract
The invention discloses an inserting-connecting torque transmission and electricity transmission split-connecting power drill rod which comprises drill rod bodies, male connectors and female connectors, wherein the male connectors and the female connectors are arranged at the two ends of the drill rod bodies. The female connectors are of a split structure, in other words, the single female connectors of the independent structure and outer tables of the drill rod bodies form circumferential rotation and axial limiting step fit through inner steps. Spline bodies in axial inserting-connecting fit are arranged at the two ends of a drill bit connector. Wire holes are formed in the oppositely-combined upper edges of the parts, at the male connectors and the female connectors, of spline body pairs. Cables and cable insulating layers penetrate the wire holes. Female contact seats and male contact seats are connected to cable ends at end openings of the spline bodies and form inserting-connecting fit, and insulating supporting seats are arranged outside the female contact seats and the male contact seats. By means of the drill rod, safety and sealing reliability of connector connection in drilling liquid are improved, mutual interference is reduced, and signal transmission is more stable. The connector electricity conductivity still cannot be reduced after the connector is repeatedly used, and meanwhile torque transmission can be conducted when the drill rod works.
